SABDINE-CAN.

To all whom it may concern Be it known that I, GEORGE A. Liner-Iron, acitizen of the United States, residing in South Boston, in the county ofSufiolk and State of Massachusetts, have invented a new and usefulImprovement in Sardine-Cans, of which the following is a specification.

This invention relates in. general to hermetically sealed containershaving a tearoff part, as for example, sardine cans and the like, and asthe invention is hereinafter described in connection with a sardine canit will be manifest that it has a much wider application and can be usedeffectively and efiiciently in containers.fornumerous other materials.

A principal object of this invention is the provision of a can forsardines and the like which may be effectively and economicallyconstructed with a double seam. at the top, obviating thereby thenecessity of closing the filled can with a soldered seam.

A further object of the invention is the provision of a container ofthis character which will have a tear-off bottom instead of a tear-offtop.

A still further object of the invention is the provision of a containerhaving a body of drawn sheet metal, a part of which has been cut awayand re-secured in place by a frangible seal.

Other objects and advantages of the invention will be apparent as it isbetter understood from the following description when considered inconnection with the accompanying drawing illustrating a preferredembodiment thereof.

On the drawing,

Figure 1 is a top plan view of a container body before the bottom of thesame has been cut away in accordance with my invention;

Fig. 2 is a section through the same;

Fig. 3 is a top plan view after the bottom part has been cut away;

Fig. 4: is a section through the same;

Fig. 5 is a similar view showing the edges about the cut-away bottombent inwardly' slightly;

Fig. 6 is a similar view showing the edges bent in completely to providea flange upon which the cut-out bottom may be seated and soldered;

Specification of Letters Patent. 1 Patented Sept. 3, 1918,

Application filed April 3, 1916.

Serial No. 88,472.

'Fig. 8 is a central section through the;

same;

Fig. 9 is an enlarged detail section taken on the line 99 of Fig. 7 andf Fig. 10 is a perspective view of the can and showing the key in place.

In accordance with my invention a sardine can body having side and endwalls 21 and 22 and bottom wall 23 is drawn in the usual manner, anoutwardly extending flange 24, later to be formed in a double seam,being provided. The bottom wall is depressed through its central part at25, the edge of said depression being spaced inwardly an' appreciableand even distance from the adjacent sideand end walls except atonecorner at 20, where the edge of the depression is spaced fartherinwardly to ward the can center. The entire bottom is first cut away asindicated in Figs. 3 and 4- and this cutaway bottomv is later secured inplace by a frangible connection, as will now be described. The bottomedge 30 of the body 28 thus left is bent inwardly first, as indicated inFig. 5 at 29, and then as indicated in Fig. 6 at'31, to provide finallya flat inwardly extending flange about the opening formed in removingthe bottom. The provision of this flange materially reduces the size ofopening so that the bottom may be laid upon these flanges, as indicatedat 32 in Fig. 8. One lower corner of the body 28 is pressed inwardly at33 and the flange 31 extends about the entire opening including thisinwardly pressed corner, the parts being finally so constructed that thedepression 25 fits in the space formed within the flange. The pointindicated at 20 in Fig. 1 of the bottom, rests inwardly at thedepression 33, the corner of the cut away bottom at this point forming atongue 34 adapted for engagement by a key 35, as will be apparent fromthe drawing. The parts so formed are soldered together to form afrangible seal, the solder 36 being laid upon the flange 31 and thebottom held thereupon to secure it in place. The top 37 is seamed at 38on the flange 24 at the top, the top having an appropriate flange 39 forengaging the flange 24. i

It will be manifest that the can thus constructed and embodying myinvention may be made by the can maker and shipped to the packer whoneed only apply the cover Witha double seamer when the filled cans areready for thisoperation.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and itwill beapparentthat various changes may be made in the form, construction andarrangement of the parts without departing fron the spirit and scope ofthe invention or sacrificing any of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.

l. A drawn sheet metal container for sardines and the like, having asealing flange at its open top edge and an inwardly extending bottomflange, and having its bottom soldered to said bottom flange of thebody, a portion of the body wall being bent inwardly near the bottom toallow a portion of said bottom to project in the form of a tongue, forripping off said bottom to open the filled and closed can. a I

2. A drawn sheet metal container for sardinesand the like, having asealing flange at its open :top edge'and an inwardly extending bottomflange, and having its bottom formed with an inset panel fitting Withinthe edge of the bottom flange of the body and being soldered to saidbottom flange, a portion of the body wall being bent inwardly near thebottom to allow a portionof said bottom to project in the form of atongue, for ripping ofl said bottom to said panel being soldered to saidbottom flange, a corner of the body wall including portions of two sidewalls being bent inwardly near the bottom to allow a corner of saidbottom to project in the form of a tongue, for ripping off said bottomto open the filled and closed can.

l. A sardine can having a drawn body, one end of said body being flangedoutward and the other end being flanged inward, a bottom secured to theinwardly flanged end having an area equal in extent to the opening insaid body before it is inwardly flanged, and a portion of the body wallbe ing bent inwardly to permit a portion of said bottom to project inthe form of a tongue.
